The so-called "water ice" style originated in Philadelphia, and proceeds from sales go to 11 S.A.Y. Detroit charities founded by Free Press sports columnist Mitch Albom. They'll have two mobile carts scooping up water ice all season at Ford Field. The store-front Water Ice Factory opened last year on Woodward in downtown Detroit, and there's frequently a line of people waiting at the counter.

"The hotter it gets, the busier it gets," said Michael Isabella, demonstrating a Ford Field food cart with his son, Daniel, on Tuesday. "It's been a great summer."
